Definitions

  • the invention relates to a sanitary shut-off or changeover valve with a valve housing body, a valve actuating member arranged axially movable thereon, and a switching device.
  • a switching device is used with a switching housing body, a switching element which is held on the switching housing body so as to be translationally movable in a switching direction from an initial position to a switching position, a restoring element which exerts a restoring force on the switching element in the switching position in the direction of the initial position, and a control element as a user interface, which is held on the switch housing body.
  • Switching devices of this type are used, for example, in sanitary fittings for switching shut-off valves installed there in various designs.
  • a rotary knob or, in general, a rotatable operating element is used as the user interface, such as, for example, the one in the laid-open specification DE 42 17 006 A1 disclosed shut-off valve.
  • Switching devices for sanitary shut-off and / or changeover valves have also already been proposed, in which a push-button or push-button acts as the control element, as in the case of the patent DE 10 2009 008 194 B4 disclosed sanitary shut-off and / or switching valve.
  • a sanitary shower head with a valve is disclosed which can be switched by the user via an operating element arranged on the shower head housing so that it can rotate and / or be axially movable.
  • shut-off and changeover valves partly for sanitary and partly for non-sanitary applications with a valve housing body, a valve actuator arranged axially movably on the valve housing body and a switching device, the switching device comprising: a switching housing body, a switching element which acts on the valve actuating element and which is movable in translation on the Switch housing body is held, a biasing spring arrangement which provides a restoring element for the switching element which exerts a resilient restoring force on the switching element, an operating pen as a user interface, which is held on the switching housing body in a tilting plane parallel to the switching direction of the switching element and can be tilted between two end positions, and a transmission unit between the switching element and the operating pen, the transmission unit having a link guide in some of these valves, which controls the tilting movement of the Operating pen converted into the translational movement of the switching element, the switching position of the switching element corresponding to an intermediate position of the operating pen between its two end positions.
  • the disclosure document CN 102 135 208 A discloses a sanitary shut-off valve which, as an on / off valve, can be switched between an open position and a closed position and has a valve housing body and a valve closing body which is held elastically axially movably on the valve housing body via a plate spring.
  • the valve closing body has a spherical cap shape and cooperates on its spherical surface with a pivotably movably held switching element of an associated switching device.
  • the switching element is actuated by a tiltable operating pen that functions as a user interface.
  • the technical problem underlying the invention is the provision of a sanitary shut-off or changeover valve of the type mentioned at the beginning with a switching device which has an alternative switching functionality compared to the above-mentioned prior art and can be manufactured with relatively little effort.
  • the invention solves this problem by providing a sanitary shut-off or diverter valve with the features of claim 1.
  • the switching device comprises a switching housing body, a switching element held on this in a switching direction from a starting position to a switching position so as to be movable in translation, a restoring element which exerts a restoring force on the switching element in the switching position in the direction of the starting position, an operating pen which as a user interface on the switch housing body in a tilting plane parallel to the switching direction of the switching element is held tiltable between two end positions, and a transmission unit between the switching element and the operating pen, the transmission unit having a link guide which converts the tilting movement of the operating pen into the translational movement of the switching element.
  • the switching position of the switching element corresponds to an intermediate position of the operating pen between its end positions.
  • the switching device further comprises a spring holder which holds the switching element on the switching housing body in a spring-elastic manner so that it can move in translation.
  • the spring holder here at the same time provides the restoring element, which then exerts a corresponding spring-elastic restoring force on the switching element in the direction of its starting position.
  • the spring holder is formed by a spring strip, which is fixed with both ends on the switch housing body and carries the switch element in a central area.
  • the switching device configured in this way has an advantageous switching functionality and can be implemented with relatively little effort.
  • the operating pen functions as a toggle switch or rocker switch, while on the other hand the switching element initiates a translational movement, i.e. a shifting movement.
  • the switching element serves as an actuator interface, i.e. as an interface to the device to be switched by the switching device, e.g. a sanitary shut-off valve or, more specifically, a valve actuator of a sanitary shut-off valve.
  • the transmission unit ensures the necessary conversion of the tilting movement of the operating pen into the translational movement of the switching element.
  • the two end positions of the operating pen can each correspond to a single starting position of the switching element or to two different starting positions of the switching element, depending on how the switching element is used is configured in this regard.
  • the sanitary shut-off or diverter valve according to the invention can be switched by the user with this switching device according to the invention by a toggle or rocker actuation of the operating pen.
  • the tilting or swiveling or rocking movement of the operating pen causes the translational movement of the switching element from its starting position into its switching position, as a result of which the valve actuating element is set in its valve-switching axial movement.
  • a shut-off or changeover valve that can be switched over by means of an axial pressure force can be actuated by a toggle or rocker switch movement caused by the user.
  • the link guide comprises a first link cam surface which is coupled in movement to the operating pin and a second link cam surface which is movement coupled to the switching element.
  • the second cam surface interacts with the first cam surface via an inclined surface coupling, whereby the desired conversion of the tilting movement of the operating pen into the translational movement of the switching element can be achieved.
  • the link guide comprises two first link cam surfaces and two second link cam surfaces, with a second link cam surface interacting with a first link cam surface.
  • the two first and the two second link cam surfaces are each arranged at a distance from one another in a direction perpendicular to the tilting plane.
  • at least two pairs of cams inclined surfaces act together at points spaced apart with respect to the tilting plane, which can contribute to a high mechanical stability and a very reliable switching behavior of the switching device.
  • the two first and second link cam surfaces can each be provided by only one or by two spaced link cams.
  • the switching device has an operating pen guide which guides the operating pen on the switch housing body in a tiltable manner.
  • the operating pen guide includes a guide surface, which is circular arc-shaped in the tilting plane, on a switching guide body that is coupled in movement to the operating pen, and a corresponding circular arc-shaped guide counter surface on the switching housing body.
  • the guide surface and the counter-guide surface consequently form interacting link guide surfaces which run in the form of a circular arc in the tilting plane as a sectional plane. This represents an advantageous link guide holder of the tiltable operating pin on the switch housing body.
  • the guide surface and the guide counter surface can e.g. be formed by corresponding cylindrical surface sections or spherical surface sections. This can be advantageous in terms of manufacturing technology and / or with regard to any sealing measures.
  • the arc-shaped guide surface on the shift guide body extends in the tilting plane over an arc angle in the range between 30 ° and 70 °. This represents an advantageous compromise for corresponding applications between a correspondingly long switching path for the stylus and a compact design of the switching device.
  • a longitudinal axis of the operating pen forms an angle of at most 45 ° with the switching direction of the switching element in all positions of the operating pen between its two end positions. This represents an advantageous design and arrangement of the operating pen relative to the switching direction of the switching element.
  • the switch housing body has a plate-shaped operating side with a recess from which the operating pin extends in all its positions between its two end positions with a longitudinal axis that encloses an angle of at least 45 ° with a plate plane of the operating side.
  • the shut-off or changeover valve according to the invention can be switched very advantageously with the aid of the switching device according to the invention.
  • the valve can be a shut-off valve that, as an on / off valve, can be switched between an open position and a closed position and in which the valve actuator is moved axially forwards or backwards for a respective switching process and, when released, moves back into an initial position, depending on System design of the valve, the starting position for the open position and the closed position of the valve can be identical or two different starting positions can be provided at different axial heights.
  • the user when the shut-off valve is in its closed position, the user can switch from its one end position to its other end position into its open position by tilting the operating pin by moving the switching element from the starting position to the switching position moves axially accordingly and then automatically moves back into the same or a different starting position with the assistance of the restoring element.
  • the user can then switch the valve back from its open position to its closed position by inverse tilting of the operating pen, the switching element again being moved from an initial position to the switching position and the valve actuating element being moved axially accordingly, in order to then automatically return to its one or only initial position .
  • the sanitary shut-off valve shown is configured as an on / off valve and can accordingly be switched between an open position and a closed position.

  • the valve actuating member 2 is implemented by a valve actuating pin 2a which extends out of the essentially cylindrical valve cartridge along an axial direction A V on one end face thereof. When the shut-off valve is closed, the valve actuating pin 2a is in a moved out starting position. From this it can be moved axially in the direction of the valve cartridge into a switch-on position by means of axial operating pressure, whereby the valve opens.
  • valve actuation pin 2a After releasing the actuation pressure on the valve actuation pin 2a, it returns axially to the same or a different second starting position, which can be, for example, an initial position that is moved out further than the first starting position in the closed state of the valve and which the valve actuation pin 2a assumes in the open position of the valve .
